To aZZ whom it may concern.-

Be it known that I, CHARLES W. ROGERS, a

citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Radiators, of which the following isa specification.

The present invention relates to that type of radiators in which the shell; is formed with corrugated surfaces to increase the radiatingsurface and nature of the apparatus.

The object of the present improvement is to provide a simple and efficient construction of a sheet or plate metal radiator more especially adapted for use in connectionwith what is generally known as the indirect system of steam-heating, and which construction is adapted with a minimum amount of sheet or plate metal and with a minimum amount of space occupied to afford a very extended amount of effective heating-surface; second, to provide a simple and efficient means for removing the water of condensation from different portions of the lower end of the radiator during the continued active use of the apparatus; third, to. provide a durable and efficient construction of parts whereby an attachment of the outletsor other pipe connections can be made with the present construction of radiator, all as will hereinafter more fully appear and be'more particularly pointed out in the claims. I attain such objects by theconstruction and arrangement of parts illustrated in the accompanying drawings, in which Figure 1 is a side elevation, partly in section, of a radiator embodying the present invention and illustrating the horizontal arrangement of the same; Fig. 2,a view one-half in end elevation and one-halfin transverse section of the same. Fig. 3 is afragmentary elevation illustrating the connection'of the drain-pipe to the radiator; Fig. 4E, afragmentary section of the same at line a: at, Fig. 3 Fig. 5 is a side elevation, partly in section, ofa vertically-arranged radiator embodying the present improvements; Fig. 6, a top plan of the same.

Similar numerals of reference indicate like As representedin the drawings, the pres ent improvements involve a convolute or scroll-shaped radiator in which the body portion is formed of two single sheets of sheet or plate metal rolled into a'volute or scroll form,

preferably of a substantially annular form in transverse section. The present invention involves the formation of the one sheet or plate 1 with end flanges 2, which are disposed in any suitable manner in a plane to one side of the main body of the sheet, so that such sheet after its formation will be of a channel form having projecting end flanges extending in a plane removed from but parallel with the surface of the body portion. In connection with the above-described construction of the plate 1, the present invention involves the formation of the companion sheet or plate 3 with corresponding end flanges 4 and with corrugations 5 in the main body of the sheet or plate and extending from flange to flange, said corrugations merging or fading into the plane surface of said flanges and arranged whollyto one side of the same, as shown.

The pair of sheets 1 andB, formed as above described, will be secured together at all four edges in a steam'tight manner by rivets or other suitable attaching means and curved or rolled into the convolute or scroll form of the present invention.

With the described arrangement of parts the'point or crown of each individual corrugation of the one sheet will be supported and sustained by the adjacent flat surface or sheet of the next adjacent convolution of the radiator-body, and this regardless of the gradual and varying curvature of such convolutions. With a radiator so formed the receiving-chamber 6 for the steam will have a volute form and with a lengthy area in one direction, and in the direction transverse thereto will have a narrow form, indented or engrailed atone side, while the air-heating passages '7 will be in the form of a multiplicity of separate passages of a lengthy nature and individual to each corrugation or indentation of the steam-receiving chamber 6 and each formed by the indented or engrailed wall of one convolution of the steam-chamber and 5o parts in the several views. the plane wall of the next adjacent convolu- 10o tion of said chamber, as clearly illustrated in Figs. 2 and 6 of the drawings.

8 is the steam-inlet pipe or duct for introducing the supply of steam to the radiator, and which is preferably connected with the exterior end of the convolute-shaped radiator casing or housing of the present invention, as illustrated in Figs. 1, 2, 5, and 6 of the drawings, in which case the outlet pipe or pipes for the exhaust-steam and water of condensation from the radiator will preferably connect with the casing or housing at an opposite end or side to that at which the steaminlet pipe is connected. It is, however, within the province of the present invention to reverse such arrangement of the inlet and outlet pipes where the judgment of the constructor or the requirements of a particular.

use may suggest such an arrangement.

While in the case of a vertically-arranged radiator constructed in accordance with the present invention and in some other instances a single outlet-pipe 9, as illustrated in Figs. 5 and 6, may serve all practical purposes, I prefer a duplex arrangement of such outlet-pipes, as shown in Figs. 1, 2, 3, and 4 of the drawings, as afiording more perfect results in an extended use or operation of the apparatus. In this 10 represents a series of branch pipes communicating with the lower end of each convolution of the steam-receiving chamber 6 and each individual to its particular convolution of such chamber. 11 is a manifold connection to which the branch pipes are connected, and which manifold is connected in any suitable manner with a receiving-tank for the water of condensation discharged from the radiator through such branch pipes and manifold. 12 representsa series of bushings in the ends of the convolutions of the housing or casing of the radiator and into which screw the branch pipes 10 to effect a substantial and steam-tight attachment. In the present improvement these bushings 12 will be secured between the attaching-flanges 2 and 4 of the respective sheets or plates composing the casing or housing of the radiator, and said flanges will be formed with semicircular ofisets, so as to form a circular cavity for receiving said bushings, the bushings being secured in said cavities in a substantial and steam-tight manner by Welding, brazing, or other Well-known and suitable means.

13 is a section of tubing adapted to form a cylindrical support or core around which the convolute radiator-body is rolled up.

14 is a filling-block of a substantially triangular shape fitting the space left at the inner end of the convolute radiator-body, as shown in Fig. 2.

15 is a filling-block of a substantially triangular shape fitting the space left at the other end of the convolute radiator-body, as shown in Figs. 2 and 5.

16 represents confining hoops or bands surof metal sheets attached together at their ends or borders, one of said sheets being formed with an attaching-border, and a corrugated main body the corrugations of which are at right angles to the direction of the longest dimension of the body and lie wholly to one side of the sheet, the other of said sheets being formed with an attaching border portion and a main body portion disposed in aplane away from such border portion, substantially as set forth.

2. A radiator or the like, comprising a pair of metal sheets attached together at their ends or borders and rolled or shaped into a convolute or helicoidal form, one of said sheets being formed with an attaching-border and a corrugated main body the corrugations of which are at right angles to the direction of the longest dimension of the body and lie wholly to one side of the sheet, substantially as set forth.

3. A radiator or the like, comprising a pair of metal sheets attached together at their ends or borders and rolled or shaped into a convolute or helicoidal form, one of said sheets being formed with an attaching-border and a corrugated main body the corrugations of which are at right angles to the direction of the longest dimensions of the body, and lie wholly to one side of the sheet, the other of said sheets being formed with an attachingborder anda main body disposed in a plane away from such border, substantially as setforth.

4. A radiator or the like, comprising a pair of metal sheets attached together at their ends or borders, one of said sheets being formed with an attaching-border, and a corrugated main body the corrugations of which are at right angles to the direction of the longest dimension of the body, and lie wholly to one side of the sheet, the other of said sheets being formed with an attaching-border and a main body disposed in a plane away from such border, and a bushing arranged in depressions in said borders to constitute an outlet for the radiator, substantially as set forth.

5. A radiator or the like, comprising a pair of metal sheets attached together at their ends or borders and rolled 0r shaped into a convolute or helicoidal form, one of said sheets being formed with an attaching-border and a corrugated main body the corrugations of which are at right angles to the direction of the longest dimensions of the body and lie wholly to one side of the sheet, the other of said sheets being formed with an attaching- Signed at Chicago, Illinois, this 27th day of border and a main body disposed in a plane February, 1901.
